How to: drive common cathode led with Arduino?

Using Arduino General Electronics
30

I feel like I'm finally getting a hold on this :slight_smile:

  • Are there any advantages/disadvantages choosing a transistor over a mosfet in this particular case? if not, I feel like buying some mosfets for the job.

I believe that both a mosfet or a transistor would allow me to still operate the driver with a PWM signal?

What values should I look out for when choosing a N-type mosfet for the job? :slight_smile:

Best regards
